It adds little to the conversation if someone just says "scared of abandonment" without providing more context. Yes, one's entitled to that opinion, but it's slightly misplaced sentiment.
Out of interest, how long would it take for one to migrate from Go to say C or Java (if Go is killed)? Similarly, how long to go from some Google cloud service to either another provider or a different other service?
I agree with you about instinctively performing a risk analysis, but was offering a different perspective that perhaps one should separate Google into a few categories, then make judgement per category.
